ATTACHING DEVICE FOR RUBBER SHOE HEELS.

Application filed September 27, 1922. Serial No. 590,834.

To a-ZZ whom it may concern:

Be it known that 1, Jo

a citizen of the United States,

Madison,

Madison, county of SEPH ABRAMowrrZ, residing at and State of Illinois, have invented a certain new and the accompanying drawing,

- thereof.

This invention relates Attaching Devices of which the followreference being had to forming a part generally to boots and shoes and, more particularly, to a certain new and useful impr ovement in attaching devices for rubber-heels or lifts to boots,

" shoes, and the like, the chief object of my present invention being to provide a simple,

readily produced, and

whereby rubber-heels or lifts facility and convenience toned upon the shoe.

1th the above and inexpensive device,

may with be detachably fasother objects in view,

my present invention resides .in the novel features of form, construction, arrangement and combination of parts hereinafter described and afterwards pointed out in the claims.

In the accompanying drawing.

Figure 1 is a plan view of the attaching-device which the stamped and formed;

Figure 2 is an edge view blank from proper is of such blank or lift with which the attaching-device proper is adapted for co-operation;

Figures 6 and 7 arelongitudinal and transverse sectional views of the heel or lift taken approximately on the lines 6--6 and 7-7, respectively, of Figure 5;

longitudinal sectional view Figure 8 is a of the attaching device and heel or in attached position upon a fragmentally shown.

Figures 3 and 5 shoe, the latter being and lift of teferring now in detail and by reference characters to the accompanying drawing,

which illustrates a preferred my invention, my presen ing device is in the form plate A by suitable blank forming dies constructed embodiment of t shoe-heel attachsubstantially of a ing, punching, and

from the flat section 1 of suitable preferably metallic material shown in Figure 1 to comprise integrally a pair of more or less elongated ribs, keys, teiions or the like 22 disposed in the same plane in the form of a cross, as best seen in Figure 3, and being substantially of dove-tail form, having preferably beveled or under-cut side walls 3, as shown in Figure l. Projecting laterally from each wall of each rib 2 at the base thereof, as shown in Figure 3, are spaced flat webs or flanges a formed with nail or tack-apertures 5, the plate A having a central threaded opening 6 and each rib 2 being suitably provided preferably at or adjacent its opposite ends with tapped threaded openings or apertures 7, for purposes shortly appearing.

Adapted for cooperation with the plate A, is a rubber heel or lift B suitably formed upon its upper face with crossed grooves or recesses 88 of dimensions and with beveled side walls 9 to snugly accommodate the ribs or keys of plate A. Gn its under face, heel or lift B is formed with preferably a plural ity of nail or screw-head cavities 10 having communication respectively with the grooves 8 by means of transverse nail or screw apertures 11. I

In use, the plate A is fitted flatwise at its webs 4rupon the exposed face of the lower fixed heel lift or shoe-sole 12, its ribs or keys :2 being presented outwardly, and rigidly and substantially permanently fastened to the shoe as by means of tacks or the like 13 projected through the openings or apertures 5 of webs or flanges at into the shoe-sole 12. A shoe-heel or lift B is now disposed with its grooves 8 presented towards ribs 2 and heel or lift B then by suitable manipulation sprung or forced into snugkey-engagement at its grooves S with the plate A at its ribs 2. By means then of preferably a plurality of headed screws or the like if projected through heel or lift apertures 11 and threaded into engagement with plate A at its openings (5 and 7, the heel or lift B is detachably secured to the plate A and thus, in turn, effectively fastened detachably to the shoe.

My new shoe-heel attaching means simple and inexpensive in form and construction, and enables the ready, convenient. and quick attachment and replacement of rubber heels, lifts, and the like upon boots 105 and shoes, without in the slightest degree interfering with or reducing the full effectiveness of the rubber-heel or lift upon the shoe and without the direct employment of nails or other such fastening means.

I am aware that minor changes in the form, construction, arrangement, and combination of the several parts of my new shoeheel attaching means may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim anddesire to secure by Letters Patent is:

1. As a new article of manufacture, an attaching-device including a pair of keys .of

dovetail formation in section, said keys intersecting one with the other on the same plane and being adapted for extended engagement throughout their length with the heel or lift, and webs projecting laterally fromsaid keys at the base thereof, the clevice being adapted to fit at said webs flatwise upon and under the shoe at the heel thereof and said webs being'provided with apertures for accommodating members for fastening the device to the shoe.

2. As a new article of manufacture, a sheet metal plate formed to include a pair of offset keys dis-posed in the same plane in intersecting cross relation and each being of hollow dovetail formation in section, and spaced webs projecting laterally from each wall of each key at the base thereof, the plate being adapted to lit at said webs only approximately fiatwise upon and under the shoe at the heel thereof and said webs be ing provided with apertures for accommodating members for fastening the plate to the shoe.

3. In combination, a shoe, a heel having a pair of intersecting beveled grooves upon its upper face, a heel attaching device including a pair of intersecting keys of dovetail formation in section and each having a threaded opening, and webs projecting laterally from said keys at the base thereof and disposed flatwise under the shoe, members having engagement with the webs and shoe for fastening the device to and upon the shoe, the plate and heel being adapted for groove and key interengagement, and screws projecting through the heel and into said keyopenings for detachably securing the heel to the shoe.

4:. In combination, a shoe, a rubber heel having a pair of intersecting beveled grooves upon its upper face, a heel attaching device including a pair of intersecting keys of dovetail formation in section and each having a threaded opening, and webs project ing laterally from said keys at the base thereof and disposed fiatwise under the shoe, members having engagement with the webs and shoe for fastening the device to and upon the shoe, the heel being adapted for sprung engagement at its grooves with said keys, and screws projecting through the heel and into said key openings for detachably securing the heel to the shoe.

In testimony whereof, I have signed my name to this specification.

JOSEPH ,ABRAMOWITZ.
